Description

This is a two-storey farmhouse from the mid-18th century, constructed of mortared rubble masonry. It features a slate roof with a rectangular dressed stone ridge stack that has dripstones and capping, located at the left (west) end of the building, positioned between the second and third windows. This stack may indicate the original extent of the farmhouse or the location of a service wing at the left end. On the right (east) gable, there is a broad external stack that is raised by a dressed stone stack above the shoulders, reaching eaves height.

The main elevation faces south and consists of a six-window range of transomed casements with slate sills. The first-floor windows are smaller and set beneath the eaves, while those in the former service wing are located in hipped roofed half dormers that interrupt the eaves line. The doorway is offset to the left end of the range and is now covered by a modern porch. Above the door, there is a datestone featuring the Vaughan shield of arms, the initials W G, and the date 1739, all within a moulded frame. At the rear of the farmhouse, there are storeyed wings that are set at right angles to either end of the main range.

The interior was not inspected during the survey.
